The nutritional value of the amaranthus seeds (Amaranthus cruentus L.) Aztek cv.
was studied. Seeds contained about 17% protein, 8% fat, 3.5% ash and 6.5% crude fibre. The
concentration of essential amino acids in crude protein were high. Crude protein had a high
level of lysine – 4.72 g · 16g–1N. First limiting amino acid (CS) was isoleucine. All the estimated
nutritional quality parameters based on amino acids composition showed that amaranthus
protein had good nutritional quality, 93% – EAAI, 2.7 – predicted PER, 74 – predicted BV.
Beneficial is also crude fat composition. Among amaranthus lipids the majority were
unsaturated fatty acids (oleic – 25% and linoleic – 49%).
